Bioinspired Postural Controllers for a Locked-Ankle Exoskeleton Targeting Complete SCI Users

Mohamed Bouri, Auke Ijspeert, Romain Pierre François Baud, Jemina Fasola, Tristan Hubert Vouga

Several lower-limb exoskeletons enable overcoming obstacles that would impair daily activities of wheelchair users, such as going upstairs. Still, as most of the currently commercialized exoskeletons require the use of crutches, they prevent the user from ...

Balance Control Strategies during Standing in a Locked-Ankle Passive Exoskeleton

Hannes Bleuler, Mohamed Bouri, Romain Pierre François Baud, Jemina Fasola, Tristan Hubert Vouga

This paper investigates sensorimotor adaptation strategies of sagittal postural control in healthy subjects under kinematic constraints. A passive exoskeleton named CAPTUR, with locked ankle joints and legs motion restrained to the sagittal plane is used t ...

Bio-inspired standing balance controller for a full-mobilization exoskeleton

Mohamed Bouri, Auke Ijspeert, Romain Pierre François Baud, Jemina Fasola, Tristan Hubert Vouga

This paper presents a novel method to perform automatic standing balance in a full mobilization exoskeleton. It exploits the locked ankle and the curved foot sole of the exoskeleton TWIICE. The idea is to use the knees to roll the sole and change the posit ...
